Structured cabling is the part of a commercial network that nobody thinks about until it fails — and when it fails, the cost is measured in hours of staff time, not in the cost of the cable. Millar Electrics designs and installs structured cabling for offices, retail, warehouses, and multi-tenancy buildings across Melbourne's eastern suburbs to TIA-568 commercial standards, with every port certified on a Fluke DSX before handover and a written port map delivered with the keys. Every termination is performed by an ACMA-registered cabler — a separate licence from electrical, required for any customer-side telecommunications cabling work in Australia.
Cat6, Cat6A, and where fibre earns its place
Cat6 is the right call for most office and retail tenancies — 1 GbE to 100 m, fast enough for everything most desks do, and quick to terminate. Cat6A doubles the bandwidth to 10 GbE at the cost of larger conduit fills, slower termination, and slightly fussier bend-radius management. We recommend Cat6A for server-room uplinks, dense WiFi 6E backhaul, AV-over-IP feeds, and any port that has a multi-year future ahead of it. For runs longer than 100 m, between racks, or between floors, fibre wins — OS2 single-mode for distance, OM4 multi-mode for short uplinks where the transceivers are cheaper. We size the backbone for the loads you have plus the loads on the roadmap, not for everything we could possibly sell you.
Comms cabinet, patch panels, and what good cable management looks like
Every install ends at a labelled patch panel inside a comms cabinet sized for the current port count plus 30 % growth. We supply and fit the cabinet (wall-mount for small jobs, floor-standing rack for medium-to-large), terminate cables onto Krone-style or modular patch panels, install horizontal cable managers between every panel pair, and bond the cabinet earth to the building MEN per AS/NZS 3000. Power into the rack runs through a metered PDU. The cabinet is left tidy enough that the next cabler in is not your problem.
Testing, certification, and the document trail
Per-port Fluke DSX certification is non-negotiable on every commercial install — wire-map, length, NEXT, return loss, insertion loss, propagation delay, all logged and exported as a PDF. Fibre links get an OTDR trace plus a bidirectional loss reading at both relevant wavelengths. The test report is delivered with the port map and the as-built drawings on handover, and we keep a copy on file. Telecommunications Cabling Advice (TCA-1) is lodged where the Telecommunications Act 1997 requires it — that paperwork is on us, not on you.
Coordinating with builders and IT
On fit-outs we attend programme meetings and work to the builder's schedule, getting cable in before plasterboard goes up and patching at fit-off. On occupied tenancies we work with the building manager on lift bookings, after-hours access, and Permit-to-Work. With your IT provider we agree port mapping, VLAN scheme, and switch-port assignment before the cables hit the panel — so go-live is plug-and-go, not plug-and-debug.
